IMPRQVEM ENT lN STEAM-VALVES! Specification forming part of LettersPatent No. 1 59,019, dated January 26, 1875; application filed November7, 1874.

To all whom it may concern: I

Be it known that I, J AMES ll. COREY, engineer, of the city of New York,in the county and State of New York, have invented a new and usefulImprovement in Steamyalvcs, of which the following is a specification,reference being had to the accompanying drawings, in which Y Figure 1 isa sectional view of a globe and valve united, withone spindle runningthrough and operating bot-h, thus showing my improvement.

Similar letters of reference indicale similar parts.

My invention relates to the construction of steam-valves, intendedparticularly for use on radiators forheating purposes; and consists incombining a supply and discharge valve, and operating both by a singlespindle, so that by turning the latter it opens and closes the top andthe bottom valve, the upper valve being for the introduction of steam orwater, the lower valve for the discharge of condensation or waste water.

The ordinary custom on radiators or coils of heating-pipes is to have avalve at each end, one being for the admission of steam, the other tocarry oli' the condensation. \Vhen two valves are so used, it becomesnecessary, for the proper operation of the heating-pipes, to have thevalves proportionately opened to each other. As they are generallyoperated by persons unaccustomed to their use, much trouble isexperienced, both in the way of noise from the collection of water inthe base, when the valves are not properly arranged, and from a loss ofheat and waste of steam in having the purge too much opened, andallowing thestea-m to blow through without performing its proper heatingfunctions.

In my valve, by one operation of the spindle, the parts must necessarilyalways be proportioned to each other-t-hc outlet to the inlet-and theproper opening always be prov ided for the condensation. The spindle hasa waste to it, so as not to leave any water in the radiator.

economical and beneficial results must ensue. A is the'inlet for thesteam. B is the passage for the steam to the radiator-pipes. O is theinlet-for the condensation'trom the radiator-pipes.' l) is the dischargefor the waste packing, as shown in the drawings, and worked with onespindle.

There are many advantages, however, to its mechanical workings in havingthe valves attached to each other, as the expansion and contraction ofthe metals are more equal.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- The globe-valve for admitting steam orwa-.

ter, in combination with the discharge-valve, provided with inlet G anddischarge D, both valves being operated by a single spindle, E,substaptially as and for the purpose set forth. In testimony whereof Ihave hereunto signed my name to this specification iu the presence oftwo subscribing witnesses.
